1. A handleset assembly for securing together linked handle assemblies of co-mounted doors each pivotably mounted at a hinge side thereof to a door frame, the handleset assembly comprising:
a first-side handle assembly including a first chassis to be mounted to a first door of the co-mounted doors, the first-side handle assembly also comprising a first rotatable component that is rotatable about an axis of rotation and that is rotatable relative to the first chassis and a first linkage element housing to be located on a side of the first door facing a side of a second door of the co-mounted doors, the first linkage element housing being rotatable along with the first rotatable component and including a first retention component; and
a second-side handle assembly including a second chassis to be mounted to the second door, the second-side handle assembly also comprising a second rotatable component that is rotatable about the axis of rotation and that is rotatable relative to the second chassis and a second linkage element housing to be located on a side of the second door facing the first linkage element housing so as to interact with one another upon bringing the first and second linkage element housings toward and proximate to one another, the second linkage element housing being rotatable along with the second rotatable component and including a second retention component;
wherein the first and second rotatable components can be operatively rotatably connectable with one another when the first and second linkage element housings are in a linked position proximate to one another by at least one linkage element provided on each of the first and second linkage element housings, and further wherein the retention components engage with one another in the linked position of the first and second linkage element housings to create a mechanical interference in an axial direction of the axis of rotation of the first and second rotatable components so as to restrict movement of the first and second linkage element housings away from one another while the mechanical interference is created.
